This invention relates to time controlledA mechanisms, and. aims toprovide novel means whereby the circuit to aparkinglight will becompleted to light the parking light' at the proper time in the'eveningand to break the circuit 4to cut off the light' at the proper time inthe morning.

An object of the invention is to provide a device of this characterwhich that 'changesin the precise embodiment of the invention hereindisclosed may bemade withinthe scope of what is claimed, with 'outdeparting from the spirit of the invention.l A I Referring to thedrawing:

ftrating .the contact ring members in circuit witha source of electricsupply.l

`Referring to the drawing in detail,- the reference 'character 5'designates aclock lor a jconstruction especially designed for 4use. on

motor4 vehicles and the type usually sup-. ported in the instrumentboard of the motor vehicle. The attachment forming the essence oftheinventonfincludes a supporting band 6 which isconstructed 'to -beslid over the body portion o the clock ,casing adjacent to the y face ofthe clock as clearlyshown'by Figure I- Mounted within .the supporting`band 'is :a ring member 7- of a diameter to closelyV t within the band6,`the ring member 7 being under surface, the contact ring 8 engagingthe right angled end 9 of the contact arm 10 of the motor vehicle, isconnected.

On the upper surface of the ring member 7 isa contact 'ring segment 12which is in 8 through thering and ring segment together, it beingstructed of brousor other insulating masupplied'with a contact ring 8'secured to its*t understood' that the ring member 7 is con- Forming apart of the member` 7 a' finger-piece 14 that extends through a slotformed in the supporting band 6 so that a person may operatethe ringmember 7 to adjust the same, 1n a manner to be hereinafter l'more fullydescribed.

The reference character 15 indicates the outerring member which is-.alsoconstructed of insulating material, the same being supplied with acontact ring 16 securedl to the under surface thereof, the contactmember 16 resting on the contact ring segment 12 to receive currenttherefrom. Pins 17v pass through the contact ring member -15 and contactring 16, where they connect with4 the contact segment 18 providingacircuit therebetween.

As clearly shown by Figure 2, the under portion of the ring member 15'is cut away throughout a portion of its diameter so that `the hour hand19 of the clock'may rest on the contact segment 12.

e member 22-Will swing from' a position 'asshown by Figure 7 to ayposition as shown The ringmember is also. providedwith a groove formed-intermeoliate lits thickness, ,there being provided aguiding finger 21atthe entrance of thegroove forguiding the hour hand into the groove,'astliefhouI-.

hand moves in the'usual; mannen At theopposite end of the 'groove 20 isa -rpivoted member 22,-which, is formed with ,a groove 23; forming-a.continuation of the groove 20 'so that as the hand passes through thegroove 20 and onto the-member 22, the

by Figure 6 spanning" the space24 to guide the hour hand 19 onto theupper surface of the ring Vmember 15 where the circuit 4is broken. A l

As clearly shown by Figures Gand 7 of I the drawing, the member 22 ispivotally sup,-l

' struction, an adjustment of the lowermost" ported at 25 and i'snormally held in a position as shown by Figure 7, or' in a position tobe engaged by the hour hand, by means ofthe spring member 2 6, whichbears thereL against.

A finger piece' indicated at 27k forms a part of the ring member .15vand also passes through a slot inthe supporting band .6 so

that this ring ,member ma be adjusted with respect to' the ring 4mem er7, to vary the time at which .the circuit is'made or broken.

The space 24- which is formed at one end of the contact segment 18,' is'formed' by cutting a notch through' the ring member 15 and-providesmeans whereby the hour hand may spring back onto the contact seg ment 12of the 'ring member Z after it has 'passedfrom the contact segment 18.,v

Thus it will be seen that due to this conring member may be made so thata greater or less portion of the segmental contact 12 may be provided atthe end of the segmental contact 18 to cause the circuit to be closed agreater or shorter length of time.

The lamp is indicated by the reference `character 28 and is in circuitwith the ring the main portion of the ring member 7,

breaking the circuit to `the lamp lt 1s obvious that by moving thefinger piece le, the ring member 8 may be adjusted to cause the circuitto be broken at, for example five oclock in the morning7 and that bymoving the outer ring member 15, the ring member-may be adjusted so thatthe,V hour 'handwill contactlwith thedsegg The wire 33;-vvichconnects-withthe ter-'- minal-B, is incircuit'withthe hour hand the.circuit may"A be vctnnplete'd astlie hour 4hand moves over thelse'gme1'1talcontacts,

. 'Assumirigtlattheclock hasbeen set as shown byl Figure 1,',thehourhand moves overthe se'gn'uentalcontactbll completing the circuitv to thelamp as longas theV hour hand engages the segmental contact-18. As

the hour hand lmoves "to, the .upper'endof the segmental Contact 18; andpasses into the the space 24 contacting with the segmental 80`space24,fthe hour 'hand will rmove through contact 12 `which isdisposed directly-thercnnder, where the circuitY isagain completed tothe lamp, the circuit remaining completed until the hour hand moves ol'ofv the Contact segment 12 at the lower end thereof.

As the hour hand continues to rotate, it will be seen, that the hourhand passes up over the-,member 21 contacting with one ."wall ofthegroove4 of the ring member 15. l whereupon the circuit remains broken.The

hour hand 'continuing to rotate in a clock-4 Wise direction, moves overthe member 22 causing the member 22 to swing to a positionjas shown byFigure 6 whereupon the hour hand moves onto the upper surface of thering'lm'ember 15 until it .contacts withy the segmental contact member18, whereu pon the circuit is again completed to light t e light.

From the foregoing it will be obvious that the operation is automaticand will Acontinue to light and cut 0H the light atpredeterminedintervals, to the end that lthe parking lamp of a motor vehicle may beautomati cally lighted in the evening, and automatically cut off in themorning.

We claim: l. In combination with the hour hand of a clock, a switchincluding upper and lower ring members mounted for rotaryv movementIover the face of the clock, said ring members being constructed offibrous materiah, a

segmental contact member carried by each ring member, one osaid ringmembers having a groove, means for' guiding the hour hand from one ofthe contact segments into the groove, and means for directing the hourhand from the groove to the upper surface of the ring member suppliedwith the groove. l

2, lln combination with the hour hand of a "clock, a switch includingring members formed of insulating Amaterial supported adjacent to theface of the clock, a segmental contact member carried on the uppersurface oi each ring member, a circular contact member on'the undersurface of each ring membei', means for completing a-circuit to the icircular contact member of one of the ring members, the circular contactmember of the opposite ring member resting on the segmental contact ofthe first mentioned ring member yto complete the circuit to thesegmental contact member of the second mentioned ring member, and meansfor directing the hour hand from one segmental contact member to theadjacent segmental contace member to complete a circuit.

3. In combination with the hour hand of a clock, a switch includingouter and inner circular contact supporting members mounted adjacent tothe face of the clock and over which the hour hand moves, said Contactsupporting members having Contact members I formed thereon, the outercircular contact supporting member' having a notch to permit the hourhand tov pass from the Contact member of the outer Contact fsupportingmember to the contact member of the inner contact support-ing member,said hour contact supporting member having a groove, a pivoted member atone end of Athe groove and` adapted to swing over' the notch to permitthe hourl hand to pass over the notch and onto the contact supportingVmember.

In testimony that we claim the foregoing as our own, We .have vheretoaffixed our signatures.
